spacmtllus formed .are arranged niullions or bziittens 14, the Width ofthe mullions b.- ing less than the space between the roof sheets. Thesemullions are arranged transversely of the car and extend from the eavestowithin a short distance of the ridge on each side of the car. n

` Each' Y pair of oppositelyI4 disposed roof sheets is pivotally mountedon the roof substructure by means of sheet metal anchor plates 15 whichstraddle the ridge of the roof and have upstanding bosses 16 formedtherein, which project into similar bosses '17. formed in the roofsheets nearr their ridge ends. The eaves ends of the roof sheetsareloosely secured to the substructure by means of angle flashingstrips 18.These flashing strips rest in a rabbet formed inthe strip. 3o

eaves end of the roof sheathing and extend fromend toV end of the cai'passing beneatl-- the Inullions and the transverse seam capsA invertedchannel `shaped 'ridge' seam caps 23 straddle the spaced ridge marginsof each adjacent pair of roof sheets and have their lower .side marginsflanged-inwardly'and upwardly forming hooked flanges 24 adapted teinterlock with the hooked flanges 22 formed in the ridge margins ofeach' sheet. The side margins of the roof sheet adjacent t0 the mullions14 are covered by transverse seam caps 25, which are similar incross-sec` tion to the ridge seam caps 23.- Tlie transverse seam 'capsstraddle the' mullions 14 and the side margins of the adjacent sheetsand have inwardly and upwardly extending hooked flanges i2G similar tothe'flanges 24 of the ridge seai'n'caps adapted to interlock with" thehooked flanges'21- formed on the *side margins of' thereof sheets. rTheeaves ends 27`of' the top portions of' the transverse seam caps are bentdown over the end of' the mullions 14 andthen turned under the adjacentdoubled-under flanges 2010i the roof sheets located on each side of' themullions. Due to the relative movement of the transverse seam caps withrespect to the roof sheets, there is a possibility o t' the turneddown'portion27 of the`se'am. cap slipping" from beneath thedoubled-underportion 20 of the roof sheets', thereby causing the sidemargins of these' partsto abut against each other and dainagethe cap. orsheets. This danger is avoidedv by making the turned! down portion 27 ofthe transverse seam cap wider thanv the distance between the side marginof the roofsheetswhen the sheets are shifted in opposite directions; Thetop portions of the transverse seamcaps have extensions 28 which lap atthe ridge and are perforated to receive the saddle bolts 29 of" therunning board saddle 30.

The ends of the ridge seanicaps and the covered by the vusual pan-shapedfour way center or corner caps 31 having an opening .infeach of theirfour walls to receive the ends ofthe ridge and transverse seam caps. The.eX-tensions 28 at the ridge ends of the transv erse seam caps haveupstanding corrugations 32 extendin cross-wise of the extensions whichare a apted t0 bear against the -under side' of the center caps 31 toprevent water being blown under the center cap and reaching the interiorof the car. These een ter caps have center holes in their top wallssurrounded by -upstanding bosses 33 through which thesaddle bolts 29pass.v Running boards 34 are securedto the'running board .saddles 30which rest on the transverse seam caps and are supported on theinullions 14 arranged beneath the transverseseain caps, thus ermittingmovement of the sheets under t ie transverse and ridge seam caps. The

running board saddles are. secured to the sub` structure by the saddlebolts 29 which extend 'down through the roof sheathing and ridge poleand are threaded to wit short distanceof their head portions. The undersides of' the running board saddles are recessed to receive the centercaps which are secured thereto byineans of clampin nuts 35. Theseclampingnuts are threa ed on the .saddle bolts 29 and are adapted tobear `against the under side of' the center cap vridge ends of thetransverse seam caps are l f 3l so as to draw thev upstanding flangesurrounding the bolt hole in the center cap up into the underside of therunningl board saddle thereby preventing leakage at these points. Thelapped portions 29 at the ridge ends of the transverse cans areoset.downwardly to provide space for the clamping nut 35 which clampsthe center cap to the under side of the running board saddle.

The bosses 17 in the roof sheets are held down on the bosses 16 in theanchor plate 15 ,by means of intermediate running board saddles oranchor saddles 36fwhich have their under sides shaped to fit the p'itchof the roof and. are provided with circular recesses 37 adapted to. fitover the bosses 17 of the roof sheets. The anchor saddles 36 straddlethe ridge seam covers Iand are secured to the substructure by bolts 38which exten-d down- .wardly tlirouglrbossed-up holes 39 in the top of'the ridge .seam caps. The bolts are.

threaded `the greater portion of their length andthe ridgeseam caps are,secured to the under side of' the anchor saddles by clamping lnuts 40,the tightening of which causes the By the arrangement described', theridge 5 seain caps and center caps can be clamped iirinly to theirrespective saddles and a tight water proof ]oint between these nieinbersobtained'irrespective of slightI variations in the milling ofthesaddles. This arrangement l also perinits the ridge seain cap andcentery dies to the car. l

l'ne turning of the eaves ends of the transverse seam under the eavesends of the root` sheets, ywhich in turn are loosely held down at theeaves by the eaves flashing strips,l

eliminates the use of all clips and bolts, and overcomes the diiiicnltyformerly encoiin tered in applying these clips to ears havingnieta-iside plates. rlhis turning under of the eaves ends of thetransverse searn caps also permits the sheets and caps to shift inopposite directions Within certain limits without becoming disengaged'from each other. The transverse seain caps are held in position on ithe ear by ineens of the saddle bolts 29 which pass thron'ghvthelappedridge ends of the seam caps. i
